We flew into Dallas at 11 PM two weeks ago and Frontier Airlines had lost our car seats. They had a few spare ones, but didn't have anything small enough for my 2 year old so we were stuck at the airport. The entire time the lady was trying to get us to use a booster seat for a 2 year old, and couldn't quite understand why I was mad (I was really mad.)
Their only solution was for me to leave my wife (4 months pregnant) and 3 kids at the airport alone at 1 in morning to buy a car seat. Which I reluctantly did because they provided no other solution.
We were told a manager would call us the next day to make things right and that we would be reimbursed for the car seat. Its now been two weeks and we haven't gotten a call. I've called and left a messages at the DFW office everyday, spoken to the national office multiple times, and emailed the receipt for the car seat multiple times; we still haven't heard from anyone at the airline.
